a space of two or three additional lines ac cording to the distance desired between the carbon copies on the record sheet. The operator then notes the point on the scale at which the pointer F stands. lle then releases the pointer E from the disk and turns said pointer until it stands at a point on the scale, counting backward from the zero point, corresponding with the distance that the pointer was turned forward from the zero point in advancing the paper. That is to say, the pointer E is placed at an angular distance backward from the zero point equal to the angular distance the pointer was turned forward from' the zero point in advz'rncine the paper; this distance having been noted by him at that time, as above stated. The angular distance between the zero mark or pointer I) and the pointer E will then be equal to the distance which it is necessary to turn'back the platen for inserting a new sheet, this distance being represented by the length of the heading on the blank hill or invoice plus the distance around the platen from the gripping roller to the striking point of the type, plus the space to be left between the carbon copies on the record sheet. The parts will now be adjusted for use in connection with the same bill or invoice heads or sheets, solong as it may be desired to use the same.

In the use of the device in printing, the bill or invoice sheet and the record sheet are insorted into the machine, with the :arbon paper between them, in the usual n'iani'rer. After the printing of the first invoice is tinishecl, on completion of the last line thereof, the sleeve F will be turned on the platen shaft to bring the pointer F thereon opposite the zero mark or pointer l) and the said pointer F Will be allowed to remain in this position. The platen will then be turned for- Ward far enough to remove the original sheet and then turned backward until the pointer F is carried past the zero-point and around the disk until it reaches the pointer E when it is stopped. The platen will then be in position for the insertion of the next original sheet which will be inserted .by thrusting it into the machine until its top edge coincs in contact with the first guide roller by which. the sheet is gripped to the platen, and the platen will then be turned forwardly to carry the record sheet and the new original sheet into position for printing, the first line on said new original sheet. It follows that by the use of the device described, the opcrator having once determined the angular distance or number of line spaces through which the platen must be turned lmckwardly before starting a new sheet into the machine, in every instance, or when insert ing each new original sheet for an original bill or invoice, is enabled to invariably turn the platen hack- Ward the same distance, according to -tho angular distance bctwwcn the zero-mark or pointer I) and the poinlcr i l on the disk. 'lhe operator will thus be able to invariably bring the first printed line of each carbon copy on the record sheet at the same distance from the last printed line of the previously made copy on said record slicci, thereby leaving uniform spaces between the several carbon copies on the record sheet.

The graduations or scalconarks on the disk are not osscnl ial or neccssany but are uselul only to enable the pointer i to be set by the operator in desired positions for origrirml sheets having headings of dill'crent widths, when the operator knows from recollection the places on the scale at which the pointer must be located For different original sheets. h'loreorcr, as the graduations correspond with the line spaces, il' tln operator desires to make the spaces between carbon copies greater or less this can be done by merely shifting the pointer E h- Jkward or forward one or more spaces as do. red.

inasmu h as the angular distance between the poinlcrs l) and i l will, in any case, corrcspond with the extent of backward turning movement of the platen required, it is immaterial whether the pointer l) or zcro mark, or the adjustable pointer l be used to mark the starting point or" the backward turning; movement. in this latter case, in first eil'ccting adjustment of the pointer E, the pointer l will be set at the zero mark when the top edge of the sheet is in contact with the lower gripping roller and the platen turned to feed tor and the paper until the paper is brought into position for printing the first line thereon, and two or three additional line spaces, to give the desired spaces between the carbon copies, in the manner bclorc described. The pointer ll will then he placed at the point on the s ale reached by the pointer h at the end of its forward tu ning movement. The distance through which the platen must be turned backward iniuscrline; each new -shcet will then. be measured bznkwardly point, and at the coniplclion ol' the last line of each bill or invoice the pointer l will be turned on the platcn-shalt to bring}; the same opposite the pointer l'l, and the platen will then, preparatory to the insertion of a new sheet, be turned backwardly until the said pointer i reaches or coincides wii h the zero point on the stationary scale.

In l ips. 5 and (3 is shown a modified form of constriuxtion in the mounting of a pointer which is adjustable on a. stationary disk and in means for holding said pointer adjustably inpositionrclalivclyto thesaid disk. in this instance, a disk is employed which is provided with ahub or sleero c that surrounds and is rigidly attached to the stationary sleeve B. 'lhc said disk is prorided with an annular recess in its inner face, and against shove the piuwu shni't nnd having it the margins part of its inner fece is mounted rotzttive ring H adopted to turn on the disk.

and the n" rein. of which projects slightly be yond the disk and is preferably knurled to eiuihie said ring to be easily turned by 1 I; j rs. Said ring H is heldeg'einst the disi: by means of a, ring I surroundingthe huh c at the inner face of the disk C and secured to .i dish by screws or otherwise; said ring an outwardly extendirg fie inrorhiys the inner nnugin oi is rin on the inner face of stud ring H the bottom of theminnhir recess in the disk is located concave, spring ring or Washer J which ined between said orts and at ."rtiei resistance to the turning oi n H on the disk (1. The said ring H pointer 11. that extends horizonteiiy he ring across the cyiindric face of the disk and terminates at the outer of said disk and ad j eccntto the scaie marks on said disk. turning said ring H on the disk, the pointer H is broughtinto any desired position on the sceie,'or, in other Words, adjusted to any desired angular position *ith respect to the zero mark on the disk. in this instance, the pointer is mounted on the platen shaft in the same manner as shown in Figs. 1, 2 and 3, these parts being like those dcscnocd'iii connection with said Figs. 1, 2 and 3 and corre indingiy iettercd on the drawing; The form of construction shown in said I 5 and i") fliifil'dS it means for adjusting the pointer H wiativeiy to the disk which may he very eesiiy and conveniently niai'iipuhited.
